PROBLEM TO BE SOLVED: To provide a compact washing nozzle fixture capable of repeating reciprocating and rotating motions at a certain angle only by supplying washing water or the like for easily realizing efficient washing works. SOLUTION: A changeover part 3 is provided which moves reciprocally and rotationally with a rotary shaft 2 as a center axis between a case part 1 having a water supply port XX fixed to high pressure water piping, etc. and the rotary shaft 2 connected with an L shape joint Z having a washing-nozzle attaching part YY with a screw for piping. An attaching shaft of a washing nozzle is rotated by a reversible driving source 9 of which the structure allows a fluid to pass through or jet to a driving device of a water wheel, etc. A compact washing nozzle fixture is constituted to jet high pressure water in alternate rotations of normal and reverse at a specified angle, by building in a mechanism which by this rotating force alternately changes over, at a certain rotation angle, a flow into the reversible driving source from a passing-through hole a1-b2 at a normal rotation to a passing-through hole a2-b1 at a reverse rotation in the changeover part 3.
